CUSHION CONSTRUCTION.

Application led Kay 14,

This invention relates particularly to elishions adapted for automobilepurposes, for sleeping car purposes, or the like.

The primary object is to provide an improved cushion of staunchconstruction which possesses important advantages from the standpoint ofcomfort and from the standpoint of durability.

The present invention constitutes a modification of the inventiondescribed in my pending application `Serial No. 109,078, filed of evendate. herewith.

The invention is illustrated in its pre-- ferred embodiment in theaccompanying drawing, in which- Fig. 1 represents a broken plan view ofthe improved cushion; Fig. 2, a broken sectional view takenl asindicated at line 2 of Fig. l; and Fig. 3,` a broken inner face view ofthe cushion-bottom.

InA the embodiment illustrated, the cushion comprises a rectangularbase-frame A which supports a bottom A; a marginal row of upholsterysprings B supported on the frame A and connected at their upper endswith a marginal rod B; an inner body of upholstery springs C supportedon the bottom A', the upper ends/of the marginal row of the inner ormain body of springs being connected with a marginal rod C; a filling ofsuitable stuiiing, or Wadding, material D, such as hair, moss or cotton,disposed above the springs; and a covering E which may comprise a ply ofburlap 1 and a inishfabric 2.

'lhe outer marginal row of springs B preferably are enclosed inindividual pockets, or coverings, of fabric 3; and the springs areunited at their upper ends by ties,or stitches, 3a. The springs B arealso connected with the marginal rod B as by means ot ties, or stitches,3".

The springs C of the main body of springs preferably are encased inindividual fabric containers 4. These springs are longer than thesprings of the outer marginal Arow B, and preferably are somewhatlighter. The springs C are connected at then' upper ends by ties, orstitches, 4a; and the springs of the marginal row of the main body ofsprings are connected vwith the marginal rod C ,by ties, or stitches,4".

The base ofthe structure comprises the rectangular fra-me A and the bottom A which may be regarded as a portion o f the 1926. Serial N0.109,079.

supporting frame, or base, of the structure. Thebottom A preferably iscomposed ot' sheet-metal. The sheet-metal member has an upturned lla-nge5 which fits within the frame A and is equipped with supporting lugs 5awhich are bent over the upper surface of the frame A and securedthereto, as by means of nails 5b.

If desired, the bottom A may be provided with perforations 6 equippedwith inwardly opening valves 62L (one shown). These valves may be ofleather secured at one point to the bottom A', as by means of a rivet6b. The valves open inwardly or upwardly to admit air when the cushionis distended; and they close to give a pneumatic cushionlng etl'ect whenthe cushion is compressed.

As will be noted from Fig. 2, the main body of springs C have theirupper endsprojecting some distance above the outer marginal row ofsprings B; also, by reason of the fact that the bottom A is depressed soas to be substantially flush with the lower surface of the frame A, thelower ends of the main body of springs extend below the lower ends ofthe outer marginal row of springs B.

'ljhe marginal row of the main body of springs C, or any desired numberthereof, are connected by ties 7 with the upper end portions of thesprings of the outer marginal iow B.

vThe covering E is stretched tautly over the springs and wedding l), andthe skirt portions 8 of the fabrics are carried downwardly and securedto the frame A as by vmeans of tacks 9. Thus, the skirt portions of thecovering furnish the usual flexible peripheral wall of the ciishoii.

lVhile the outer marginal row of springs B is anchored to the marginalrow ot the main body of springs, there is a certain independent actionof the main body of springs when the cushion is occupied. 'lliis is duepartly to the. greater length of the main ody of springs, partly to themanner in which they are connected with the outer marginal row ofsprings, and partly to the fact that the outer marginal row of springspreferably are heavier, or stronger, than the main body of s rings.Otherwise stated, the main body o springs will yield readily and conformto the person, while the outer row of springs will offer more resistanceand tend to give a certain desired firmness of support t0 the limbsvnear thel knees. This uo f action will occur without inconvenience tothe erson seated on the cushion, owing to the act that the marginal rowof the inner main bod of will yieldv rather readily when the person isseated. Moreover, the

outer marginal row of springs tends to pre- The improved cushion is aself-sustaining structure which may be placed upon any suitable support.The improved cushion may be made of necessary length and of the rightproportions to serve as a seat cushion or as a back cushion in asleeping car berth, where the advantages noted are highly desirable.

What I regard as new, and desire to secure by Letters Patent, is:

1. A cushion comprising a base, an outer marginal row of upholsterysprings mounted on said base, fabric coverings enclosing the individualsprings of said row, an inner main body of upholstery springs mounted onsaid base and rising a substantial distance above said outer marginalrow of springs, individual fabric coverings en closing the individualsprings of said main body of springs, a marginal rod secured to thelupper 'end portions. of the outer marginal row of springs, a marginalrod secured to the upper end portions of the marginal row of the mainbody of springs, ties connecting the upper portions of the outermarginal row of springs and the adjacent intermediate rtions of themarginal row of the main y of springs, stuing material above said groupsof springs, and a fabric covering enclosing the stuiling material andsprings and secured to said base.

2. A cushion vcomprising a base, an inner `main body of relatively lightupholstery springs encased in individual fabric coverings, said springsbeingnested in close contact with each other and connected b an outermarginal row of relatively stiff upholstery springs encased inindividual fabric casings contacting with each other and connected byties, said last-named springs having their upper ends disposed asubstantial distance below the plane of the upper ends ties,

of the main body of springs, a marginal rod connected with the upperends of the marginal springs of said main body of springs, a marginalrod connected with the upper ends of said outer row of springs, tiesconnectinjg the upper ends of the outer marginal row o springs with theadjacent intermediate portions ofthe marginal springs of the main bodyAof springs, stuiling material above the groups of springs mentioned,and a fabric covering enclosing the stufling material and springs andsecured to said base.

3. A cushion comprising abase consisting of a marginal frame-member anda relatively thin bottom secured to said framemember so as to besubstantially flush with the lower surface of said frame-member, an`louter marginal vrow of upholstery springs mounted on said base, fabriccoverings enper portions of the outer marginal row of a springs and theadjacent intermediate portions of the marginal row of the main body ofsprings, stuffing material above said groups of springs, and a fabriccovering enclosing the stuiling material and springs and secured to saidbase.
